Sam is tired of waiting so long, his waiting heart is not so strong. Until patience grows down deep inside and joins him on the waiting ride.

There is an invisible tree that lives inside of me
It wants to grow big and tall even though I am very small

Patience - the fourth book in the Invisible Tree series for 2-5 year olds, beautifully captures the journey of waiting and the discovery of the virtue of patience found on the way.
